Why do we say that the sun is life?

The sun is life sentence we have heard repeatedly and may never wonder why? If it is actually true or just a social stereotype phrase emerged only pleasure that brings us exposure to its warm rays.

Remember Easy Science footnote No. 49 where he spoke of the need of vitamin D

This vitamin is involved

v In absorption of phosphorus (P) and calcium (Ca + +) in the intestine so that favors the growth of both bones and teeth.

v The immune system protection.

v in the regulation of calcium levels (Ca + +) that is essential for central nervous system and muscles working properly. Avoiding cramps and seizures.

Sunlight is the major source of this vitamin because it transforms a substance found under the skin (7 dehydrocholesterol) in pro-vitamin D3 and cholesterol ergo pro-vitamin D2 for both then through another chemical process are transformed into vitamin D.

So

sunlight promote the synthesis of this vitamin is so necessary for our life.
But it is important to note that no we should abuse it as permanent and prolonged exposure can damage the genome of the skin and cause cancer (melanoma).

care of the skin from the sun is essential to preserve our health

This why? still needs an answer

Let

remembering another note No. 158 Easy Science where we talked about the balance of our atmosphere gaseous general composition is given by

Nitrogen --- 78.03 --- % Oxygen
-------- 20, 99% carbon dioxide
----- 0, 03%
and other rare gases with water vapor

0.94% -----

is necessary that the atmospheric gases are kept in balance for good preservation of life, disruption of these percentages significantly detrimental to the biome.
Oxygen

Oxygen is an important gas for the biome of the planet. The animal kingdom is used in the process of respiration. Breathe in, absorbing oxygen carried by blood each cell of a living organism, so that becomes effective combustion of food and generate the energy needed to hold everything that involves life, from the maintenance of metabolism (chains of chemical reactions of the living organism) to all actions that a living being done throughout his life.

The plant kingdom expel oxygen during the day and absorb carbon dioxide offsets process and balances the respiration of the animal kingdom. That atmospheric oxygen is released by plants in the f otosíntesis, where one of its stages indispensably required the presence of sunlight to generate as product of the decomposition of the plant absorbs water through their roots, this gas. At a later stage called dark period because it requires the presence of light the plant fixed carbon dioxide as a nutrient (glucose) and produces several substances that serve more to live.

If the sun were not present , this process would not, as the kingdom plant transforms light energy into chemical energy to promote their own life, but the result is the benefit of the animal kingdom. Without the sun the plant kingdom in the world disappear, so would the animals that depend on it and the subtle balance of atmospheric gases descompensaría, creating chaos in the global biome.

The sun is the developer of plant life, which in turn is the lung of nature.

entire planet lives and maintains a delicate balance that must be respected by the man, ambition and ignorance led to alter what had been achieved over millions of years of evolution and therefore suffer the consequences now. Climate change, loss of biodiversity, water pollution, soil and air are the result of carelessness on the planet.

need to know to respect and ensure respect the conditions that make the world a place fit for the present life and future generations.

Man is just a dot on the vast Universal but has an important purpose of being
